torchfunc is library revolving around PyTorch with a goal to help you with:
- Improving and analysing performance of your neural network
- Daily neural network duties (model size, seeding, performance measurements etc.)
- Plotting and visualizing modules
- Record neuron activity and tailor it to your specific task or target
- Get information about your host operating system, CUDA devices and others
Quick examples
- Seed globaly, Freeze weights, check inference time and model size
# Inb4 MNIST, you can use any module with those functions
model = torch.nn.Linear(784, 10)
frozen = torchfunc.module.freeze(model, bias=False)
with torchfunc.Timer() as timer:
frozen(torch.randn(32, 784)
print(timer.checkpoint()) # Time since the beginning
frozen(torch.randn(128, 784)
print(timer.checkpoint()) # Since last checkpoint
print(f"Overall time {timer}; Model size: {torchfunc.sizeof(frozen)}")
- Recorder and sum per-layer activation statistics as data passes through network:
# MNIST classifier
model = torch.nn.Sequential(
torch.nn.Linear(784, 100),
torch.nn.ReLU(),
torch.nn.Linear(100, 50),
torch.nn.ReLU(),
torch.nn.Linear(50, 10),
)
# Recorder which sums layer inputs from consecutive forward calls
recorder = torchfunc.record.ForwardPreRecorder(reduction=lambda x, y: x+y)
# Record inputs going into Linear(100, 50) and Linear(50, 10)
recorder.children(model, indices=(2, 3))
# Train your network normally (or pass data through it)
...
# Save tensors (of shape 100 and 50) in folder, each named 1.pt and 2.pt respectively
recorder.save(pathlib.Path("./analysis"))
For performance tips, plotting and other check torchfunc documentation.
Installation
pip
Latest release:
pip install --user torchfunc
Nightly:
pip install --user torchfunc-nightly
Docker
CPU standalone and various versions of GPU enabled images are available at dockerhub.
For CPU quickstart, issue:
docker pull szymonmaszke/torchfunc:18.04
Nightly builds are also available, just prefix tag with nightly_. If you are going for GPU image make sure you have
nvidia/docker installed and it's runtime set.
